将时间戳转换为mysql格式

Question

我有一个格式为“ 2020-01-30T14：55：52.373959Z”的日期时间，并且我正在尝试插入一个出现以下错误的sql数据库；

mysql.connector.errors.DataError: 1292 (22007): Incorrect datetime value: '2020-01-30T14:55:06Z' for column `edb`.`flight_path`.`time_stamp` at row 1

所以我尝试用以下内容转换日期；

import time
import datetime
json_time = value.get('gatewayTimestamp', time.time())
print(json_time)
time_stamp = datetime.datetime.fromtimestamp(json_time).strftime('Y%-%m-%d %H:%M:%S')
sql = "insert into flight_path values (%s)"
cursor.execute(sql, (time_stamp)

出现此错误：

2020-01-30T14:55:52.373959Z
